There are several tools that help you search through the monthly "Who is Hiring" posts on Hacker News. The primary difference with this one is it includes chat, semantic search as well as a semantic map visualization (select "business" from the dropdown and expand to get a sense of how this can be used). Behind the scenes it uses LLM instructions in batch to extract, format, tag the job posts, computes UMAP after everything settles while of course making everything searchable.
You can use the basic text search to quickly filter the results or alternatively use semantic search (toggle via the button in the search bar).
Finally, you can chat with the job postings as well (click the Chat button). It has a basic RAG type pipeline but also includes some tools which make it possible to ask broader questions like "What are the general themes in the job postings this month?" and dig down from there.
Anyway, I hope people find this useful. Any feedback is welcome (either here directly or feel free to use the contact page here https://nthesis.ai/contact which dog foods the same mechanism - no contact info required).
If you want to build something similar there is an API and a nice (in my opinion) CLI tool than can be used to ingest data, search or chat as well.
